BACKGROUND 1. Technical Field

The present disclosure relates generally to playing digital mediacontent and, more specifically, to techniques and systems for creating adynamic playlist for managing the playback of digital media content.

2. Introduction

In recent years, electronic devices capable of playing digital musichave become commonplace. For instance, electronic devices such as laptopcomputers, handheld digital media players, smart phones, and handheldgaming systems are used daily by society to listen to music. As a resultof the growing popularity of these electronic devices, the sale ofdigital music has grown dramatically. Users can utilize various avenuesto access digital music, including visiting an online store to purchasedigital music as a single track or a complete album. Users can alsoshare their music with one another or stream music online.

As the amount of digital media available to a user increases, improvedtechniques must be applied to organize and manage this information.Traditionally, playlists have been used to organize the music intocollections, and, through a selection of a song or through a selectionof a playlist from such collections, the music can be played. Theplaylists would be stored persistently and be selectable by the consumerwhen he or she wishes to play the songs associated with the playlist.However, these traditional techniques are very limiting in that theyrequire the overhead of creating a playlist and storing it. Moreover,the traditional playlist environment is not well suited for dynamicchanges to a consumer's desires. For example, assume that a student isplaying music from a playlist in his dorm room. His friend comes intohis room and wants to listen to a song that is not in the currentlyplaying playlist. Traditionally, selecting the one song to play wouldterminate playback of the playlist or the song would be added into thepersistent playlist, thus becoming a part of the playlist. Both of thesebehaviors are undesirable to the student, who would like to continuelistening to his playlist after his friend listens to the song, andwould not desire to have the friend's selection added to his playlist.

While there have been many advancements in the use and distribution ofdigital media, there is still a need for improved techniques formanaging playback of digital media.

SUMMARY

Additional features and advantages of the disclosure will be set forthin the description which follows, and will become apparent from thedescription, or can be learned by practice of the herein disclosedprinciples by those skilled in the art. The features and advantages ofthe disclosure can be realized and obtained by means of the disclosedinstrumentalities and combinations as set forth in detail herein. Theseand other features of the disclosure will become more fully apparentfrom the following description, or can be learned by the practice of theprinciples set forth herein.

Disclosed are systems, methods, and non-transitory computer-readablestorage media for intelligently managing the playback of digital media.The digital media can include audio songs, videos, movies, images,photos, and other digital media content. An intelligent dynamic queue isconfigured to manage the playback of digital media. A user can submitrequests to playback digital media (from a single source or varioussources) by adding the digital media to the queue. Depending on thedigital media added and the process used to add the digital media, thedigital media can take on different properties. The media playbackapplication can manage the handling of the digital media in the queue byutilizing a queue status field that is associated with each digitalmedia item in the queue. In some examples, the queue can containmultiple entries that specify the playback sequence. Each entry can beassociated with a digital media item and can also include a queue statusfield. The queue status field stores a variable describing whether thedigital media item associated with the entry is manually queued (i.e.,the digital media item was explicitly added to the queue) orautomatically queued (i.e., the digital media item was implicitly addedto the queue via a predetermined collection, such as a playlist).

In one embodiment, some entries in the queue can be purged (e.g.,deleted) when a triggering event occurs. Exemplary triggering eventsinclude changing the media source or adding a collection of digitalmedia to the queue. For example, the media playback application can beconfigured to purge the queue when the media source changes, when analbum is added to the queue, when a playlist is added to the queue,and/or other scenarios. The determination of which entries to purge candepend on the queue status field of each entry. In one example, entriesin the queue that have a queue status field set to manual entry remainin the queue because the user explicitly requested the digital mediaitem. In contrast, entries that have a queue status field set toautomatic entry are deleted from the queue because they wereautomatically added into the queue. In some embodiments, the queuestatus field of a digital media item in the queue can be updated asother digital media items enter the queue.

DETAILED DESCRIPTION

Various embodiments of the disclosure are discussed in detail below.While specific implementations are discussed, it should be understoodthat this is done for illustration purposes only. A person skilled inthe relevant art will recognize that other components and configurationsmay be used without parting from the spirit and scope of the disclosure.

The present disclosure addresses the need in the art for systems,techniques, and methods for improved playback management of digitalmedia. The digital media can include digital songs, movies, videos,podcasts, music videos, images, photos, and other digital media content.While the disclosure focuses on playback management for digital songs,it is to be understood by a person of ordinary skill in the relevant artthat these teachings also apply to playback management for other formsof digital media such as movies, images, videos, photos, podcasts, etc.

The present disclosure focuses on an intelligent queue that is used by amedia playback application to manage the playback of digital mediaitems. An intelligent queue is different than a traditional playlist. Anintelligent queue can contain media items from multiple media sources,some of the sources being remotely located. If one of the remote sourceswere to go offline, the integrity of the queue is not affected since theintelligent queue is configured to skip songs that are offline. Incontrast, a traditional playlist generally contains only items that arelocally stored on a playback device. Playlists can sometimes play backmedia from multiple sources however, when one of the sources go offline,the playlist's integrity is lost. Moreover, an intelligent queue can bedynamically modified by adding other media items into the queue in realtime whereas modifications to a playlist are persistent in that they arestored in memory. Furthermore, the intelligent queue is capable ofinterpreting the user's intentions based on where the user adds digitalmedia into the queue and as a result, affect how other media items inthe intelligent queue are handled.

In some examples, different types of digital media can co-exist in asingle queue. For example, a queue can include a song and a video thatare presented in a specified playback order. A user can submit requeststo a media playback application to add songs (or other types of digitalmedia) from a single source or from various sources to the queue. Eachsong can be linked or otherwise associated with an entry in the queue.Besides adding an individual digital media item, entire playlists,albums, and other collections of music can be selected for addition tothe queue. When the collection of music is added, the digital mediawithin the collection are added to the queue. Playback of music by themedia playback application can be based on the queue and morespecifically, the order that the songs appear in the queue. Since theuser can in real time add digital media to the queue, the queue isdynamic and changes constantly based on the user's desires. In someembodiments, the queue is also persistent in that un-played tracks thatare in the queue when the media playback application closes will remainqueued for playback the next time the media playback application opens.

Through the intelligent queue, the media playback application is capableof seamlessly changing in between two different modes of operation. In afirst mode, the media playback application operates in a normal playbackmode. In the normal playback mode, the media playback application beginsby playing the first song in the playlist and continues to sequentiallyplay through the tracks in the playlist until the last song is played.In a temporary playback mode, songs can be dynamically entered andplayed back in a specified order. When the list is done, playback iscompleted and the list is cleared. Traditionally these different modesof operation have been mutually exclusive however through the use of theintelligent queue, the media playback application is able to seamlesslyswitch between the two modes according to actions items and triggeringevents initiated by the user. For example, dragging a song into thequeue can result in the media playback application transitioning from anormal playback mode to the temporary playback mode. Once the song hascompleted, the media playback application can transition back to thenormal playback mode. Therefore, the media playback application iscapable of operating in a normal playback mode that does not requireuser interaction and then subsequently change to a temporary playbackmode when a request is received to listen to a song. Listening to thesong does not abandon the normal playback mode. Instead, the mediaplayback application returns to the normal playback mode when the songhas completed.

The media playback application can associate queue status fields to asong when the song is added to the queue. More specifically, each entryin the queue can store information related to a song. For example, theinformation can include a link to the song and a queue status field ofthe song. Depending on the queue status field associated with the song,the song can be handled differently by the media playback application.In one embodiment, each entry can include a queue status fieldconfigured to identify whether a song was manually entered orautomatically entered. Manually entered songs can remain in the queuewhen the source of music changes. As another example, songs that wereautomatically entered into the queue can be purged from the queue whenthe source of music changes. The media playback application interpretsmanually entered songs as songs that the user has explicitly selected tolisten to, either now or in the future. In contrast, songs that areautomatically entered (e.g., queuing songs from an internet radiostation such as Pandora® or queuing songs from a playlist) generallybelong to a collection of songs that share a commonality, thecommonality being that the songs all belong to a collection that wasselected by the user to be added to the queue. Since this commonality isthe reason that the songs were added to the queue (and not because theuser has manually selected each song to be added into the queue), thesesongs are volatile and in some instances can be deleted from the queuewhen the source changes or when the media playback application closes.Examples of songs that are automatically entered into the queue includethe situation where a user selects a playlist to be added to the queueor where the user requests the media playback application for ten songsthat are similar to a selected seed song. The recommended songs areadded to the queue. In some examples, the media playback application caninclude rules for editing the behavior of the media playbackapplication, such as setting the circumstances when the type (manuallyentered or automatically entered) should be changed in an entry.Additional details about automatically entered and manually enteredsongs are discussed below.

Media Playback Application

FIG. 1 illustrates an exemplary media playback application. The mediaplayback application can be an application running on a client devicethat is capable of playing back digital media. Exemplary media playbackapplications include the iTunes® media player. Media playbackapplication 100 includes content bar 110, browser window 140, queue bar150, and currently playing bar 160. Content bar 110 is configured todisplay music that is available to the user. Using browsing window 140,a user can browse the music from a source and select one or more songsthat the user would like to listen to. Selected songs can appear inqueue bar 150 for scheduled playback. Queue bar 150 can be hidden ordisplayed using show/hide upcoming songs button 142. In some examples,queue bar 150 can be a pop up screen rather than a side bar, where thepop up screen can be activated or deactivated through a display optionsuch as show/hide upcoming songs button 142.

In one embodiment, content bar 110 can be organized into sources 120 andplaylists 130. Sources 120 display a list of sources of music that areavailable to the user. Here, the sources include local music library 122(e.g., music library that the user has stored locally on his device),home share 124 (e.g., music from the music libraries of other users onthe same network), streaming 126 (e.g., music that the user streams fromremote sources, such as internet radio stations), and cloud storage 128(e.g., music stored remotely that the user has rights to play or isotherwise associated with the user). Available music that is not storedon the user's local device can be accessed through Wifi, Bluetooth,Intranet, Internet, and other connection options. In other embodiments,other types of media can exist in the sources, such as movies and TVshows. However for simplicity, only audio tracks are discussed. A personof ordinary skill in the art would be able to expand the teachings hereto other types of media, such as movies, images, podcasts, videos,photos, etc.

Playlists 130 shows a list of playlists that are available to the user.The playlists can be generated by the user or automatically generated bya third-party service, a remote server, or the media playbackapplication. Here, playlists 130 include DJ playlist 132, playlist A 134and playlist B 136. Playlist A 134 and playlist B 136 may include acollection of songs that are available to the user from sources 120. DJplaylist 132 can include a collection of songs that was automaticallygenerated by the media playback application or a remote server. In oneembodiment, the media playback application automatically creates thecollection of music based on parameters provided by the user. Forexample, top rated songs can be added and prioritized by placing them ina higher queue position than other songs. In some examples, DJ playlist132 can be dynamically generated whenever the playlist is selected. Thiscan allow DJ playlist 132 to take advantage of up to date metadata whenautomatically selecting the songs to play. In other examples, DJplaylist 132 can be generated or regenerated based on user request.

Queue 150 displays an ordered list of songs for playback. The songs inthe list can be from multiple sources or multiple playlists. The orderthat the songs appear in queue 150 is the playback sequence of thequeue. When a currently playing song is finished or about to be finishedplaying on a media player device, the next song in the queue isretrieved for playback. For media stored remotely (i.e., not stored onthe user's device), the media playback application can pre-fetch apredetermined number of songs in the queue from the remote source andstore them locally for future playback. This may improve performance byreducing the opportunity for the music to refresh or lag duringplayback. The retrieved song is removed from the ordered list and theremaining songs in the list are promoted up one cell. Since songs can bedynamically selected and added into the queue, queue 150 also is dynamicin nature. Thus, a user can add songs into the queue. In other examples,other people using other devices can add songs to the queue. Queue 150can also be persistent, thus allowing songs that were scheduled forplayback to be presented to the user the next time the user starts themedia playback application.

Here, queue 150 includes entries 152, 154, and 156, each identifying asong from a particular media source. The three songs 152, 154, and 156are located under heading 153 titled “Up Next.” The songs are presentedin a specified playback order. Thus, the next song to be played is thesong identified by entry 152, followed by the song identified by entry154, followed by the song identified by entry 156. In some examples,heading 153 can also present other information associated with theorigin of this grouping of songs. For example if the songs are all partof a playlist, the name of the playlist can also be presented in heading153. This can be useful to provide additional information about thecollection of music that the user is currently listening to. In someexamples, each entry 152, 154, 156 can display additional informationabout the song in an auxiliary view that is displayed when a cursor isplaced over the song. For example, queue 150 may by default beconfigured to display the title of the song and the duration of thesong. However when the cursor is placed over the entry, song metadatasuch as lyrics, artist, genre, rating, etc. can also be displayed in anauxiliary view. In other examples, hidden action items that can beperformed on the entry can also be presented when the cursor is placedover the song or the cursor rolls over the song/entry. For example,action items such as skip song, promote song to play next, promote songto play immediately, rate song, create a playlist by using the song as aroot song, and others can be presented to the user when the cursor isplaced over the song/entry. In other examples, one or more of theseaction items can be fixed on the entry and presented along with thedefault information displayed. Here, entry 156 presents shortcut 157along with the title and duration (i.e., default information). Shortcut157 can be linked to a predefined or user defined action item associatedwith the song such as skip song or move song to play next. In someexamples, shortcut 157 can appear on a rollover.

Queue 150 can also include a history icon 151. History icon 151, whenselected, presents a list of songs that have been previously played bythe media playback application. The list of previously played songs caninclude songs from different sources and playlists. In one embodiment, apredefined minimum play time can be applied to songs that are partiallyplayed to determine whether the song should be added into the history.For example, a user who is sampling songs from his music library (i.e.,quickly listening to a few seconds of a song for purposes of evaluatinga song or selecting songs to be added to a playlist or other container)may not want the sampled songs to be included into the history sincedoing so may clutter the history. As another example, a user who listensto the first few seconds of a song may decide to skip it and not wishfor the song to be displayed in the history. This can be prevented bysetting minimum play time parameters that are to be met before a song isadded into history. For instance, a minimum play time parameter maystate that a song must be played for 10 seconds before it is added intothe history. In some examples, the list of upcoming songs shown in queue150 can be replaced with the list of items that have been previouslyplayed when history 151 is selected. In other examples, the informationpresented for each song in history can vary depending on the source orplaylist. For example, radio sources can present the name of the radiostation and optionally the name of the song. As another example, aplaylist can be associated with a color scheme, icon, or otheridentifier. In the history, songs from that playlist can be presentedwith the identifier. Media playback application can also include window160 configured to display the currently playing song. As songs finishand the next song is fetched from the queue, the song presented inwindow 160 can change. In some examples, queue 150 can be configured toalso display the currently playing song in a entry above banner 153.

Queue 150 can be presented as a window of a given size. The size of thewindow can be fixed or dynamic. In one embodiment, the size of thewindow can dynamically change based on the size of the GUI of the mediaplayback application or other windows of the media playback application.For example, as the media playback application is resized by the user,queue 150 can also be resized. The number of entries presented in queue150 can also vary depending on the size of queue 150. If there are moreitems in the queue (or history) that can be presented in the number ofentries available, different UI techniques such as a “show more” optionto see additional pages of items or scroll functionality can beimplemented to view or access those additional items.

Intelligent Media Queue

FIGS. 2a and 2b illustrate an exemplary queue. The exemplary queue canbe presented on a graphical user interface. As described above, a queueis a data structure configured to manage an ordered list of media itemsfor playback, where the media items may be located or stored atdifferent sources. The order that the media items appear in the queuecan represent the playback sequence of the media items. The queue mayhave functionality and properties that are user-configurable to assistin improving the user's experience while listening to music. Forinstance, action items or metadata associated with a song can beconfigured to be displayed on the respective entry of that song. Asshown in FIG. 2a , empty queue message 290 can be presented when queue200 is empty. Empty queue message 290 can be configured to provideinstructions on how to use the queue. For example, empty queue message290 can include a message “When music is playing, this area showsupcoming songs. You can add, remove, or rearrange songs as you go.”Empty queue message 290 can also provide instructions on how to add aplaylist or other collection of music to the queue.

As shown in FIG. 2a , playlist 210 has been selected by a user to beadded to queue 200. Playlist 200 is a collection of music containingsongs 211 to 215. Each song can include metadata describing the songsuch as song title, artist, album, composer, genre, rating, year, andothers. In one example, playlist 200 can be a manual type playlist likea mixed tape or a playlist that is manually populated by the user. Inanother example, playlist 200 can be a smart type playlist that isautomatically populated based on search criteria such as genre, year,artist, ranking, or other attribute or theme. In some cases, there maybe underlying logic to the combination of music while in other cases,there may be no logic to the creation of the playlist. As such, it isdifficult for the media playback application to determine whether theuser is selecting the playlist because the user wishes to listen to alltracks in the playlist or alternatively wishes to just listen to aplaylist in a similar fashion as a person listening to a radio station(where it is the dominant theme or genre of the playlist rather than theindividual tracks that the user wishes to listen to).

In some examples, the media playback application can use heuristics todetermine whether the playlist is being added for the specific trackswithin the playlist or for the dominant theme of the playlist. Dominantthemes can be songs that are highly ranked, songs having the same genre,songs that have the same artist, or songs that have any other commontheme, When the playlist is selected for its theme rather than theindividual tracks in the playlist, the tracks in the playlist can bepurged from the queue when the user wishes to listen to something else(e.g., another playlist, album, or other collection of music.) Forexample, purging can remove tracks that were automatically entered intothe queue. For instance, adding a smart type playlist to the queueresults in a plurality of non-user selected being added into the queue.If the user wishes to listen to a single song, a detour can be createdin the queue where the song is played followed by continued playback ofthe playlist. If the user does not switch to something else, the songsin the queue can be played in sequential order.

While a playlist is described here, the heuristics can also be appliedto other collections of music, such as albums and smart playlists (e.g.,playlists that have been automatically generated based on one or moreseed songs). In some examples, user settings can be set to define howthe media playback application handles different collections. Forexample, user settings can define that songs within a particular type ofcollection should be treated as an automatic entry or a manual entry. Asanother example, the user settings can define that a type of collectionhaving more than a predefined number of media items should have allitems within the collection be treated as automatic entries. A song canhave a queue status field that can be set to manual entry or automaticentry. Manual entry is a song that the media playback applicationinterprets as a song that the user has made a conscious decision tomanually enter into the queue. A manual entry can be treated differentlythan an automatic entry (e.g., a song that gets automatically added intothe queue based on a user's selection of a collection of music). Forexample, the user settings or rules can define the media playbackapplication's behavior when a playlist, album, or other collection ofmusic is added to the queue. Default settings can also be set when theuser has not defined the user settings. When media is added to thequeue, the media can be animated as it enters the queue, thus creatingthe appearance that the media is being physically added to the queue.

FIG. 2b illustrates queue 200 after playlist 210 has been added. When aplaylist or other collection of songs is added to an empty queue, themedia playback application enters a passive playback mode. In thepassive playback mode, the application populates the queue with songsfrom the collection of songs when space is available in the queue andcontinues to play music from the collection of songs until all songs areplayed. Here, a user setting specifies that when a playlist is added toa queue, songs belonging to the playlist are to be treated as automaticentries. As shown, queue 200 includes banner 220 that reads “Up Next:From Playlist 210.” This informs the user that the songs in the list arefrom playlist 210. The media playback application can sequentially playsongs from queue 200 based on the sequence they appear in queue 200. Forexample, playback will begin with song 211 which resides in the firstentry of the queue, followed by song 212 which resides in the secondentry of the queue, followed by song 213 which resides in the thirdentry of the queue. Each song can include a queue status field (235,245, 255) describing whether the song was manually entered (“M”) orautomatically entered (“A”). As shown in FIG. 2b , the songs added fromplaylist 210 are treated as automatic entries based on a user setting.As such, songs 211, 212, and 213 are all marked as an automatic entries(see queue status field 235, 245, and 255, respectively), as shown bythe letter “A.” In another example where a radio station is added to theplaylist, banner 220 can read “Up Next: From Radio Station <name>.”Below, each entry can present a short description of the radio station,thus preventing the user from knowing the name of the song beforeplayback.

The media player may pre-fetch a predetermined number of songs from theradio station or other remote source. The predetermined number can beset to a small value to minimize wasted costs from fetched songs thatare not played back. The predetermined number can also be set to a largeenough value to prevent poor playback performance due to periods of slowdownloading speeds or periods of inability to communicate with theremote source. In some examples, the predetermined number can bedynamically updated based on the performance of the remote source andthe client device running the media playback application. For example,the media player application can increase the predetermined number whenpoor playback performance is experienced due to poor wireless service.This can occur when the client device is located in a metropolitan citywith many users or in the mountainside where reception is sparse. Byincreasing the predetermined number of media items that are buffered,the media playback application is capable of not communicating with theremote source for a longer period of time and therefore lowering thelikelihood that the buffer will be depleted before the client device isable to communicate with the remote source. As another example, thepredetermined number can be decreased when the media playbackapplication determines that the number of songs that are fetched but notplayed back is greater than a given threshold. In some examples, thepredetermined number can be temporarily increased (or decreased) andsubsequently returned to its original value.

In some examples where the collection being added to queue 200 containsmore media items than the number of entries in queue 200, the mediaplayback application can automatically populate entries in the queuewith songs from the collection when the entries become available. Forexample, queue 200 can be populated with songs 211-213 of playlist 210when playlist 210 is added into queue 200. When song 211 transitions tobeing currently played, songs 212 and 213 are promoted up an entry, thusleaving the last entry empty. As a result, song 214 is added to queue200 to fill the available entry. In other examples, additional pages ora scrolling functionality can be implemented to view songs 214 and 215.

In some examples, the music player application may analyze a request toadd a collection of songs before the collection of songs is added intothe queue. Various rules can be applied during the analysis. Forexample, the media playback application may analyze the number of songsin a playlist before adding the songs to the queue. If the number ofsongs is greater than a predefined limit, a prompt can be presented tothe user to confirm whether the user intended to add the songs to thequeue. As another example, the type of the container can be used in theanalysis. For instance, a prompt can be presented when adding a playlistbut not presented when adding an individual song or album.

FIGS. 3a and 3b illustrate another exemplary queue. The exemplary queuecan be presented on a graphical user interface. Queue 300 can be similaror substantially similar to queue 200 of FIGS. 2a and 2b . As shown inFIG. 3a , instructions have been received to add three songs (songs 310,320 and 330, in that order) to queue 300. Each song has been manuallyselected for queue 300. The resulting queue after adding in the songs isshown in FIG. 3b . As shown, the songs appear in the queue in the orderthat they were selected. More specifically song 310 is listed as thefirst song, song 320 is listed as the second song, and song 330 islisted as the third. Each entry also has a queue status field specifyingthat all three songs are manually entries “M” (queue status field 355,365, and 375, respectively). When songs are manually selected and addedto an empty queue, the media playback application enters an activeplayback mode. In one example, all entries into the queue are treated asmanual entries when in active playback mode. Thus, in addition toindividual songs, a collection of songs entered into the queue are alsotreated as manual entries. In another example, automatic entries canalso enter into the queue when in active playback mode. For example,selection of a playlist to add to the queue without specifying thelocation to add the playlist to the queue can result in the playlistbeing appended to the end of the queue and the tracks within theplaylist being treated as automatic entries. In contrast if the locationto add the playlist into the queue is specified, the tracks within theplaylist can be treated as automatic entries. Thus, the manner in whichsongs are entered into the queue can affect the attributes associatedwith the song and in turn the manner in which the media playbackapplication handles these songs. Songs that enter the queue via acollection may be added as automatic entries when in a passive playbackmode but as manual entries when in an active playback mode. Thus, theuser setting and the playback mode can affect the queue status fieldassociated with the songs added.

Banner 340 of queue 300 provides a synopsis of the upcoming tracks inthe queue. Here, banner 340 is configured to display the number ofmanually entered songs in the queue that are coming up. In contrast whenthe upcoming songs are automatically entered songs (or when the mediaplayback application is in a passive playback mode), banner 340 isconfigured to display the title of the collection that the songs belongto (e.g., playlist title, album title, radio station title, etc.). Thus,the information presented on the banner of queue can vary depending onthe songs in the queue and/or the playback mode.

Queue Actions

FIGS. 4a and 4b illustrate an example of skipping a song in a queue. Theexemplary queue can be presented on a graphical user interface. A usercan trigger the skip command by rolling over an entry or by selecting askip option associated with the entry. Queue 400 can be similar orsubstantially similar as queue 300 of FIGS. 3a and 3b and queue 200 ofFIGS. 2a and 2b . As shown in FIG. 4a , there are currently songs 410,420, and 430 of queue 400. As illustrated by queue status fields 415,425, and 435, each of these songs were automatically entered into queue400 (“A”). Command 405 is received to skip song 420. FIG. 4b illustratesqueue 400 after the entry associated with song 420 has been removed. Asshown, the entry for song 430 has been promoted in queue 400 and now isnext to song 410. In some examples, a skipped song may not be added tothe queue history unless user settings specify otherwise. As shown,skipping a song does not affect the attributes of the songs stored inother entries.

In some examples, skipping a song can alter the queue status field ofother entries in the queue. For example, the media playback applicationcan interpret the action of skipping a song in the queue as meaning thatthe user wishes to listen to the songs not skipped. If the user did notwant to listen to the other songs in the queue, the user could haveskipped those songs also. As a result, songs that remain in the queueafter a skip command can be converted to being manually entered. In oneexample, only entries in the queue above the skipped song are convertedto being manually entered since it is possible that the user is glancingover the list from the top down. As such, only the queue status fieldsof songs above the currently skipped song are candidate to be altered.Entries that have a queue status field of manually entered can bepreserved in the queue when the queue is purged.

FIGS. 5a and 5b illustrate an example of adding a song to a queue. Theexemplary queue can be presented on a graphical user interface. The songcan be added into the queue through various trigger mechanisms, such asthe selection of an action item associated with the song or dragging anddropping the song into the queue. In one embodiment, the song can beadded at a specific location (e.g., entry) in the queue according to theuser command received. For example, an action item associated with thesong can be triggered by a user command which causes the song to beadded as the next song to be played in the queue, to play now (e.g.,cancel current song and play this song), or to add to the end or anyother location in the queue.

In one embodiment, the media playback application can include a ruleconfigured to treat all songs that appear before the newly added song assongs that should be played in the queue. The user has deliberatelyadded the song after these songs and thus, it can be presumed that theuser would like to hear all the songs placed before the location of theadded song. Thus, the media playback application can convert anattribute of songs in front of the added song that were originally setas an automatic entry into a manual entry.

Here, queue 500 can be similar or substantially similar to queue 400 ofFIGS. 4a and 4b , queue 300 of FIGS. 3a and 3b , and queue 200 of FIGS.2a and 2b . As shown in FIG. 5a , queue 500 includes songs 510, 520, and530 and each song was automatically added into queue 500 (attributes515, 525, and 535 set as “A” for automatic entries). Banner 505 ispresented to inform the user that a playlist including songs 510, 520,and 530 is currently playing, with each of songs 510, 520, and 530 beingan automatic entry. The name of the playlist can be displayed here aspart of Banner 505. A command is received to add song 540 at a locationin between songs 510 and 520 of the playlist. For example, song 540 canbe dragged from the music library and dropped in between song 510 andsong 520 of queue 500. Upon receiving this command, the media playbackapplication can shift songs 520 and 530 downstream, thus makingavailable an entry in queue 500 for song 540. As shown in FIG. 5b , song540 is now associated with an entry that is located in between song 510and song 520.

When a song is manually added to a queue while the media playbackapplication is in a passive playback mode (i.e., the entries in thequeue are automatic entries), the media playback application can enter amixed playback mode. When the media playback application is in a mixedplayback mode, songs that are scheduled to play before the currentlyadded song can have their queue status field set to manual entry, ifnecessary, to signify that the user has made a conscious decision toplay all the songs queued above the currently added song. This ensuresthat song 540 and all songs in the queue above song 540 (e.g., song 510)are played by the media playback application in the specified order. Inother words, songs that are set to manual entry are not purged. Afteradding in song 540, queue 500 now includes both manual entries andautomatic entries. In some embodiments, a queue having multiple types ofentries can include separate banners for each type of entry. Forexample, manual entries can be grouped together and associated with onebanner while automatic entries can be grouped together and associatedwith another banner. Here, banner 503 is configured to describe themanual entries. As shown, banner 503 describes that there are two queuedsongs to be played next. Similarly, banner 505 is configured to notifythe user that after these two manually queued songs, the media playbackapplication will return to the playing music from the playlist. Here,the name of the playlist can be displayed. If the playlist hasadditional songs not present in the queue, they can be added into thequeue as entries in the queue become available. In some examples, allactions to add songs into the queue are treated as manual entries oncethe user has manually entered songs into the queue. This is becausetreating entries as automatic entries may destructively clear the manualentries from the queue.

In some embodiments, the shuffle command may take on differentfunctionality based on the type of entries in the queue. For example, ifthe queue contains both manual entries and automatic entries, a shufflecommand performed may only shuffle the automatic entries in the queue.This is because the manual entries were placed in a specific order bythe user and thus, should be played back in that order. As anotherexample, the performance of the shuffle command can be based on both thetype of entries in the queue and the currently playing song. Forexample, if the currently playing song is a manual entry, all the manualentries in the queue can be shuffled. Similarly if the currently playingsong is an automatic entry, all the automatic entries in the queue canbe shuffled. User defined options can be configured to override thisdefault behavior.

While the example illustrated in FIGS. 5a and 5b show adding in a songto a queue, similar techniques can be applied to add in a playlist, analbum, or other collection of songs. The collection of songs would beadded to the playlist at the specified location. For example if aplaylist containing four songs were added in between the third andfourth entry of the queue, the four songs in the playlist would resultin occupying the fourth, fifth, sixth, and seventh entry slots in thequeue. The song (or songs) can come from various sources including aninternet radio station, home share, streaming, other user's library,cloud storage, and other sources. Depending on the source, differenttechniques can be used to present song information on the entry. In oneembodiment an internet radio station that is added into the queue candisplay the name of the radio station on an entry instead of displayingthe name of a song. The radio station name may be displayed instead ofthe specific name of the song for various reasons. For example, the songbeing played by the radio station changes as the radio station entry inthe queue moves to the currently playing position. Since it is difficultto determine the song that will be played when the entry of the radiostation is promoted to the currently playing position, it is logical touse the name of the radio station on the entry instead of the name ofthe song. In another example, the radio station may not want the user toknow the name of the upcoming song. This can prevent the user fromwaiting for an upcoming song that the user wishes to acquire and thencopying the song as the song is played. A single entry can remain in thequeue as songs from the internet radio station continue playing, wherethat single entry is configured to inform the user of the internet radiostation that is currently being played. For example, the entry can state“Up Next: More from the XYZ station.” When songs are manually queued,the single entry representing the internet radio station can be pusheddownstream under banner 505 to notify the user that after the manuallyqueued songs, playback will return to the radio station. When the sourcechanges or another playlist is selected, the radio station can beremoved from the queue.

Besides adding songs into the queue, actions can also be performed toexisting songs in the queue. In some embodiments, different actions canbe performed on songs in the queue to change the order orproperties/attributes of the songs in the queue. Exemplary actionsinclude drag and drop, play next, and play immediately. For example,drag and drop can move the song from the drag location to the droplocation. As another example, play next can move the song from itscurrent location to the first entry in the queue. As yet anotherexample, play immediately can be a combination of two actions. The firstaction is similar to a play next command where the song is promoted tothe first entry in the queue. The second action can be skipping thecurrently playing song. Therefore, the queue and the attributes of thesongs within the queue can change depending on the action performed.

In one embodiment, the media playback application can includeintelligence that is used when processing a request to place a song(either an existing song in the queue or adding a song from a source) asthe next song in the queue. When a user adds a song to a queue, adetermination is made as to whether the user intended the song to beadded as the next song to be played or if the user intended the song tobe added at the end of a logical collection of songs, one of which iscurrently being played. A logical collection of songs in some instancescan be considered a single work. Since the collection of songs isconsidered a single work, they are treated as belonging to a singlecontainer that the user intends to listen to in sequence. Examples of acontainer of songs include albums and smart playlists (playlistsautomatically generated, sometimes based on a theme or trait) containingsongs that have similar traits (artist, genre, year, ranking, etc.)based on a selected seed song. For example, if the currently playingsong is part of an album, the intention of selecting an action item toplace a song as the next song in the queue may be for the song to playfollowing the playing of the album. In some examples, a playlist canalso be considered a container. In some examples, heuristics can be usedto determine when a collection of music is considered a container ofmusic. These heuristics can be based on user settings that have been setto differentiate a container of music form a collection of music.Exemplary user settings can include a limit to the number of songs thatcan exist in a container, the similarity of metadata between the songsin the container, and other factors. In some examples, the mediaplayback application can apply container rules to determine when acollection of music is a container. These rules can be weighted inmaking the determination. Exemplary rules can include a weighting factorif the artist is the same in the collection of music, another weightingfactor if the album name is the same in the collection of music, anotherweighting factor if the genre is the same in the collection of music,another weighting factor if the ratings provided to the songs aresimilar within a predetermined range, and others.

FIGS. 6a, 6b and 6c illustrate an example of adding a song into thequeue as the next song to be played. The exemplary queue can bepresented on a graphical user interface. Queue 600 can be similar orsubstantially similar to queue 500 of FIGS. 5a and 5b , queue 400 ofFIGS. 4a and 4b , queue 300 of FIGS. 3a and 3b , and queue 200 of FIGS.2a and 2b . As shown in FIG. 6a , queue 600 includes song 610, song 620,and song 630, in that order and each song is an automatic entry (queuestatus fields 615, 625, and 635, respectively, set to “A”). Banner 601is configured to notify the user that the upcoming tracks (e.g., songs)are from playlist. FIG. 6a also illustrates the media playbackapplication receiving instruction or request 650 to play song 640 as thenext song in the queue. At this point, the media playback applicationcan make a determination whether one or more of the songs in the queueare part of a container with the currently playing song.

FIG. 6b illustrates an example of queue 600 when the songs in the queue(e.g., songs 610, 620, and 630) are determined to not be part of acontainer with the currently playing song. As shown, song 640 is addedinto the queue in the first slot and thus will be the next song played.Since song 640 was manually selected by the user, queue status field 645of song 640 is set with an queue status field of manually entered. Therest of queue 600 has shifted downstream one position to make room forsong 640. As such, songs 610, 620, and 630 have moved down one slot inqueue 600. Since the newly added song was not placed behind any existingentries in queue 600, none of the existing queue status fieldsassociated with the songs in the queue (e.g., queue status fields 615,625, and 635) are altered. As shown in FIG. 6b , queue 600 now has twotypes of entries in the queue. Banner 603 is configured to providedetails about the manually entered songs while banner 605 is configuredto provide details about the automatically entered songs. Banner 605presents information associated with the collection that the rest of thequeue belongs to. More specifically, banner 605 presents the name of theplaylist added to the queue that results in songs 610, 620, and 630being added to the queue.

FIG. 6c illustrates another example of queue 600 when the songs in thequeue (e.g., songs 610, 620, and 630) are determined to be part of acontainer with the currently playing song. This is the opposite of theexample shown in FIG. 6b . As shown in FIG. 6c , a determination is madethat songs 610, 620, and 630 belong to the same container as thecurrently playing song. The determination can be made by comparingmetadata of the currently playing song with metadata of songs 610, 620,and 630. For example, heuristics can be applied by the media playbackapplication to determine whether certain properties of songs 610, 620,and 630 are the same, similar, or related to the properties of thecurrently playing song. In some instances each property can have adifferent weighting factor. A similarity value can be generated fromcomparing the properties of the songs and summing up the weight values.The similarity value can in turn be used to determine whether a song andthe currently playing song belong to the same container. Exemplaryproperties include artist name, album name, genre, year, ranking, tracknumber (checking if the track numbers of the upcoming songs are insequential order), bit rate, and others. For example, the artist nameproperty can be assigned a weighting factor of 0.8, the album nameproperty can be assigned a weighting factor of 0.8, the genre propertycan be assigned a weighting factor of 0.7, the year property can beassigned a weighting factor of 0.3, and the bit rate property can beassigned a weighting factor of 0.2. A comparison can be made between thecurrently playing song and song 610 where the weighting factors assignedto similar properties between the two songs are summed together. If thesum of the weighting factors is greater than 1, the songs are determinedto belong in the same container and thus should not be separated in thequeue.

Here, the media playback application may, as a result of the heuristics,determine that the currently playing song and songs 610, 620, and 630belong to the same container and thus are required to be played togetherbefore other songs can be played. Since the container has already begunplaying the currently playing song, the remainder of the container (song610, 620, and 630) are played before any other song is played. As aresult, the ordered list of songs in queue 600 is song 610, song 620,song 630, and song 640. The media playback application may determinethat song 640 is a manual entry because it was manually selected andentered into the queue by the user. As such, queue status field 645 isset to “M” for manual entry. In one example, the media playbackapplication can subsequently determine that there are three songs infront of manually entered song 640. Based on a rule stored on the mediaplayback application, songs in front of a manually entered song can beconverted into manual entries. As a result, queue status fields 615,625, 635, are converted to manual entries.

FIGS. 7a and 7b illustrate an example of an action performed on a mediaitem in a queue. The exemplary queue can be presented on a graphicaluser interface. Queue 700 can be similar or substantially similar toqueue 600 of FIGS. 6a, 6b, and 6c , queue 500 of FIGS. 5a and 5b , queue400 of FIGS. 4a and 4b , queue 300 of FIGS. 3a and 3b , and queue 200 ofFIGS. 2a and 2b . As shown in FIG. 7a , queue 700 includes banner 701notifying the user that the songs scheduled for playback belong to theplaylist. The name of the playlist can be displayed in banner 701. Queue700 includes four songs ordered as song 710, song 720, song 730, andsong 740. Each of these songs includes a queue status field identifyingthem as automatic entries (queue status fields 715, 725, 735, and 745,respectively).

As shown in FIG. 7a , a command of play next action 750 is received andassociated with song 730. The media playback application can receive thecommand along with the desired location in the queue. In response to thecommand, the media playback application can move the selected song tothe first position or spot in the queue. Songs that were originally infront of the selected song can be pushed one slot downstream as theselected song moves up the queue. As shown in FIG. 7b , the mediaplayback application has moved selected song 730 to the first positionin the queue and songs 710 and 720 have been pushed downstream oneposition. The resulting queue order is song 730, song 710, song 720, andsong 740. In one embodiment, the media playback application can changeone or more queue status fields of the selected song when the selectedsong is promoted to be played next in the queue. For example, queuestatus field 735 that is associated with song 730 can be set to manualentry (see queue status field 735 set to “M” in FIG. 7b ) to identifythe song as a song that was manually entered into the queue. Thus, songattributes can change during manipulation of the queue, thus changinghow the media playback application will treat the song. As shown in FIG.7b , the songs in the queue have been grouped into automatic entries andmanual entries. Banners 703 and 705 are configured to presentinformation associated with song 730 and songs 710, 720, and 730,respectively.

FIGS. 8a and 8b illustrate an example of another action performed in amedia item the queue. The exemplary queue can be presented on agraphical user interface. Queue 800 can be similar or substantiallysimilar to queue 700 of FIGS. 7a and 7b , queue 600 of FIGS. 6a, 6b, and6c , queue 500 of FIGS. 5a and 5b , queue 400 of FIGS. 4a and 4b , queue300 of FIGS. 3a and 3b , and queue 200 of FIGS. 2a and 2b . As shown inFIG. 8a , queue 800 includes banner 801 and an ordered list of songsincluding song 810, song 820, song 830, and song 840. A commandincluding drag and drop action 850 is received from the user. Drag anddrop action 850 moves a song from a current entry to a new entry. Inother words, the drag and drop action moves the song from a first slotin the queue to a second slot in the queue. Here, song 820 is beingdragged from the second queue position and dropped after the fourthqueue position. FIG. 8b illustrates the resulting queue after drag anddrop action 850. As shown, song 820 has been moved behind song 840, thusresulting in queue 800 having the playback order of song 810, song 830,song 840, and song 820. In one embodiment, the media playbackapplication can also change the queue status field of songs that are tobe performed before a drop position to manual entry. Since the user hasspecified a slot to play a particular song, it is presumed that the useralso wants to play all songs that appear ahead of the particular songalso. As a result, the media playback application can convert queuestatus fields 815, 835, 845, and 825 to manual entries (“M”) since thesequeue status fields are associated with songs that are played before theselected song (e.g., song 810, song 830, song 845, and song 820,respectively). Since the songs in the playlist have been converted tomanual entries, banner 803 is displayed in queue 800. Banner 803notifies the user that the next four upcoming songs are all queued songs(e.g., manually entered). As discussed below, the media playbackapplication may treat manually entered songs different thanautomatically entered songs.

In some embodiments, the media playback application can periodicallypurge (i.e., delete) songs from the queue. Purging entries in the queuecan be a housekeeping technique performed by the media playbackapplication to maintain the quality of the queue. In some examples, asong can be purged from the queue based on the how the song entered thequeue. For example if the song was a manual entry, it is confident thatthe user desires to listen to the song. As a result, manual entries arenot purged. In contrast if the song was an automatic entry, it isuncertain whether the user desires to listen to this specific song or tothe collection that the song belongs to. As a result, automatic entriesare purged. Automatically entered entries can have a lower priority overmanually entered entries since it is unclear whether the songs wereadded into the queue because the user selected a collection thatcontains the song or the user intended to play the song. Songs withhigher priority can be played before songs with lower priority. In oneexample, the automatically entered entries can be considered volatileentries and can be replaced when a triggering event occurs, such asswitching the playlist or the source.

In one embodiment, rules can be generated by the media playbackapplication to control the purging behavior of the queue. For example, arule can be created to purge the queue of automatic entries whenever thesource changes. The media playback application can interpret the user'scommand to change sources as an implicit notification that the user nolonger wishes to listen to music from the previous source. As a result,automatic entries which the user did not explicitly add are removed fromthe queue. In another example, a rule can be created where the queue ispurged of automatic entries whenever a collection of media is added tothe queue. The collection of media, which can be a playlist or album,can include a plurality of songs. The media playback application caninterpret the addition of this collection of media to the queue asmeaning that the user is done listening to a previously selectedcollection of music. As a result, the media playback application canpurge the automatic entries from the queue.

FIGS. 9a and 9b illustrate an example of purging media items from aqueue. The exemplary queue can be presented on a graphical userinterface. Queue 900 can be similar or substantially similar to queue800 of FIGS. 8a and 8b , queue 700 of FIGS. 7a and 7b , queue 600 ofFIGS. 6a, 6b, and 6c , queue 500 of FIGS. 5a and 5b , queue 400 of FIGS.4a and 4b , queue 300 of FIGS. 3a and 3b , and queue 200 of FIGS. 2a and2b . As shown in FIG. 9a , queue 900 includes four songs: song 910 thatis queued next for playback and songs 920, 930, and 940 that belong tothe playlist. Queue status field 925, 935, and 945 of songs 920, 930,and 940, respectively, inform the media playback application that thesongs were automatically entered into the queue (“A”). Similarly, queuestatus field 915 informs the media playback application that the song910 was manually entered into the queue. When a triggering event occursthat causes the media playback application to purge the queue, songscontaining a queue status field of being automatically entered aredeleted from the queue. Exemplary triggering events include changing themedia source or adding a collection of digital media to the queue. Forexample, the media playback application can be configured to purge thequeue when the media source changes to an internet radio station, whenthe media source changes to a remote source, when an album is added tothe queue, when a playlist is added to the queue, and/or otherscenarios. As shown in FIG. 9b , songs 920, 930, and 940 have beendeleted from the queue. Song 910 remains since queue status field 915states that the song was manually entered. In some examples, thecurrently playing song can also be skipped as the user transitions to adifferent media source or collection of music. Some triggering eventscan result in new songs being added into the queue. Depending onspecified location (if any) of the songs entering the queue, song 910can be played next or played later in the queue.

In some embodiments, the queue can also be configured to present ahistory list containing songs that have been previously played by themedia playback application. The history list can be configured topresent a list of songs previously played from newest to oldest. A usercan review the previously played songs and decide to purchase orre-queue certain songs for playback. Songs that were skipped or purgedduring playback are not added into the history list. In some examples, apredefined limit of time can be used by the media playback applicationto determine whether a song should be added to the history list. Forexample, a song that is played for less than 10 seconds is not added tothe history list. Songs may be played for less than 10 seconds becausethe user was sampling music and song was skipped during playback or thesong is no longer available. A song can be no longer available if thesource of the song is no longer online. In some examples, the mediaplayback application may try to find other sources that contain thesong, such as the user's media library. If the song cannot be found inthe available sources, then the song is skipped from the queue.

FIGS. 10a and 10b illustrate an example of a queue with a history list.The exemplary queue can be presented on a graphical user interface.Queue 1000 can be similar or substantially similar to queue 900 of FIGS.9a and 9b , queue 800 of FIGS. 8a and 8b , queue 700 of FIGS. 7a and 7b, queue 600 of FIGS. 6a, 6b, and 6c , queue 500 of FIGS. 5a and 5b ,queue 400 of FIGS. 4a and 4b , queue 300 of FIGS. 3a and 3b , and queue200 of FIGS. 2a and 2b . As shown in FIG. 10a , queue 1000 includessongs 1010, 1020, 1030, and 1040. The songs are in position n+1, n+2,n+3, and n+4, respectively, where n is the currently playing song. Queue1000 can include header 1001 and banner 1003. The header 1001 can beconfigured to display buttons for various options of queue 1000. Forexample, header 1001 can include clear button 1002 which clears thequeue and history button 1004 which shows the history list of queue1000. Banner 1003 can be configured to notify the user that four queuedsongs are scheduled for playback. In some examples, banner 1003 can alsoprovide additional information on the next song scheduled to play. Insome examples, the buttons can be configured to remain hidden until thecursor rolls over header 1001. In other examples, a button can beconfigured to remain fixed on header 1001.

FIG. 10b illustrates an example of queue 1000 of FIG. 10a after the userhas selected to view the history list. This can occur when the usertoggles history button 1004 of queue 1000. As shown, queue 1000 nowdisplays header 1005. Header 1005 includes the text “HISTORY” to notifythe user that the history list is currently being displayed instead ofthe queue. Header 1005 can include clear button 1006, which clears thehistory, and back to queue button 1008 to return back to the queue.Songs 1050, 1060, 1070, and 1080 are presented in the history list. Asshown, the songs appear sequentially based on playback order with themost recently played song on the top and the least recently played songon the bottom. Action items that can be performed on a song can bepresented next to the song. For example, song 1060 can include purchasebutton 1065 to purchase the song. Similarly song 1070 can includere-queue button 1075 to re-queue the song. The song can be re-queued as“play now”, “play next”, or “add to queue” depending on the user'sselection or default settings. The action items available to a user candepend on the status of the song. For example, the purchase button maynot be available for songs that already exist in the user's medialibrary. In some examples, songs in the history cannot be dragged anddropped to alter the order that the songs appear in the history list.

In one embodiment, the source of the song can affect the way the song ispresented in the history list. For example, radio stations can bepresented differently in the history list and the queue than othersources. A radio station can appear in the queue without specifics onthe song that will be played. When the radio station is moved to thecurrently playing song, the name of the song is presented to the user.After the song has played, the song enters the history list. In thehistory list, the name of the song appears along with an option topurchase the song. The option to re-queue the song may not be providedto the user until the user owns a copy of the song.

Queue Sharing for Multiple Devices

In one embodiment, a queue on a host device can be accessed by multipleclient devices. Each client device can view the queue and optionally,edit the queue by adding songs, playlists, or other collections of musicinto the queue. In one example, a voting option is presented where themultiple client devices can vote on songs. Songs that meet certainvoting criteria (such as minimum number of votes, minimum number oflikes, or minimum average voting score) can be promoted in the queue toplay next. In one example, songs promoted in the queue have a queuestatus field set as manually entered while other songs entered by themultiple client devices have a queue status field set as automaticallyentered. This allows only songs that are desirable by the community tobe promoted up the queue. In another example, statistics from the votingcan be used to analyze the songs in the queue. The statistics can beused to provide additional options to the users, such as “play highestranked songs more often.”

Methods

FIG. 11 illustrates an exemplary method for adding a song to a locationin the queue. Process 1100 begins by receiving a request to add a songto the queue (1110). After the song is received, a determination is madeas to the location in the queue the requester wishes to add the song(1120). Once the desired location in the queue is determined, a query isperformed to determine if it is necessary to edit songs in the queue(1130). It one example, songs in the queue can be edited when there aresongs above the song being added into the queue. In another example,songs in the queue can be edited when the queue is in a passive playbackmode. If a determination is made that the songs in the queue are to beedited, process 1100 can continue to edit the state field of the songs(1140) and subsequently add the new song into the queue (1150).Alternatively if there is no need to edit songs in the queue, the songcan be added to the desired location (1150).

FIG. 12 illustrates an exemplary method for adding a song as a next songin the queue. Process 1200 begins by receiving a request to add a songas the next song in the queue (1210). Process 1200 can then determine ifone or more songs in the queue are part of a container with thecurrently playing song (1220). If one or more songs in the queue arepart of the container (1230), then the song is added into the queueafter the songs in the container (1240). Alternatively if none of thesongs are part of the container (1230), then the song is added as thenext song in the queue (1250).

Cloud Computing System

Cloud computing is a type of Internet-based computing in which a varietyof resources are hosted and/or controlled by an entity and madeavailable by the entity to authorized users via the Internet. Anexemplary cloud computing system configuration 1600 is illustrated inFIG. 16 wherein a variety of electronic devices can communicate via anetwork for purposes of exchanging content and other data. The systemcan be configured for use on a wide variety of network configurationsthat facilitate the intercommunication of electronic devices. Forexample, each of the components of system 1600, in FIG. 16, can beimplemented in a localized or distributed fashion in a network.

System 1600 can be configured to include cloud computing resources 1620(i.e., “the cloud”). The cloud resources can include a variety ofhardware and/or software resources, such as cloud servers 1622, clouddatabases 1624, cloud storage 1626, cloud networks 1628, cloudapplications, cloud platforms, and/or any other cloud-based resources.In some cases, the cloud resources are distributed. For example, cloudstorage 1626 can include multiple storage devices. In some cases, cloudresources can be distributed across multiple cloud computing systemsand/or individual network enabled computing devices. For example, cloudcomputing resources 1620 can communicate with servers 16041, 16042, . .. , 1604 n (collectively “1604”), database 1606, and/or any othernetwork enabled computing device to provide the cloud resources.

Furthermore, in some cases, the cloud resources can be redundant. Forexample, if cloud computing resources 1620 is configured to provide databackup services, multiple copies of the data can be stored such that thedata is still be available to the user even if a storage resource isoffline, busy, or otherwise unavailable to process a request. In anotherexample, if cloud computing resources 1620 is configured to providesoftware, the software can be available from different cloud servers sothat the software can be served from any of the different cloud servers.Algorithms can be applied such that the closest server or from theserver with the lowest current load is selected to process a givenrequest.

In system 1600, a user interacts with cloud computing resources 1620through user terminals 1602 ₁, 1602 ₂, . . . , 1602 _(n) (collectively“1602”) connected to a network by direct and/or indirect communication.Cloud computing resources 1620 can support connections from a variety ofdifferent electronic devices, such as servers; desktop computers; mobilecomputers; handheld communications devices, e.g., mobile phones, smartphones, tablets; set top boxes; network-enabled hard drives; and/or anyother network-enabled computing devices. Furthermore, cloud computingresources 1620 can concurrently accept connections from and interactwith multiple electronic devices. Interaction with the multipleelectronic devices can be prioritized or occur simultaneously.

Cloud computing resources 1620 can provide cloud resources through avariety of deployment models, such as public, private, community,hybrid, and/or any other cloud deployment model. In some cases, cloudcomputing resources 1620 can support multiple deployment models. Forexample, cloud computing resources 1620 can provide one set of resourcesthrough a public deployment model and another set of resources through aprivate deployment model.

In some configurations, a user terminal 1602 can access cloud computingresources 1620 from any location where an Internet connection isavailable. However, in other cases, cloud computing resources 1620 canbe configured to restrict access to certain resources such that aresource can only be accessed from certain locations. For example, ifcloud computing resources 1620 is configured to provide a resource usinga private deployment model, then cloud computing resources 1620 canrestrict access to the resource, such as by requiring that a userterminal 1602 access the resource from behind a firewall.

Cloud computing resources 1620 can provide cloud resources to userterminals 1602 through a variety of service models, such as Software asa Service (SaaS), Platforms as a service (PaaS), Infrastructure as aService (IaaS), and/or any other cloud service models. In some cases,cloud computing resources 1620 can provide multiple service models to auser terminal 1602. For example, cloud computing resources 1620 canprovide both SaaS and IaaS to a user terminal 1602. In some cases, cloudcomputing resources 1620 can provide different service models todifferent user terminals 1602. For example, cloud computing resources1620 can provide SaaS to user terminal 1602 ₁ and PaaS to user terminal1602 ₂.

In some cases, cloud computing resources 1620 can maintain an accountdatabase. The account database can store profile information forregistered users. The profile information can include resource accessrights, such as software the user is permitted to use, maximum storagespace, etc. The profile information can also include usage information,such as computing resources consumed, data storage location, securitysettings, personal configuration settings, etc. In some cases, theaccount database can reside on a database or server remote to cloudcomputing resources 1620 such as servers 1604 or database 1606.

Cloud computing resources 1620 can provide a variety of functionalitythat requires user interaction. Accordingly, a user interface (UI) canbe provided for communicating with cloud computing resources 1620 and/orperforming tasks associated with the cloud resources. The UI can beaccessed via an end user terminal 1602 in communication with cloudcomputing resources 1620. The UI can be configured to operate in avariety of client modes, including a fat client mode, a thin clientmode, or a hybrid client mode, depending on the storage and processingcapabilities of cloud computing resources 1620 and/or the user terminal1602. Therefore, a UI can be implemented as a standalone applicationoperating at the user terminal in some embodiments. In otherembodiments, a web browser-based portal can be used to provide the UI.Any other configuration to access cloud computing resources 1620 canalso be used in the various embodiments.
